This paper draws upon data from a research project, undertaken in 2 Year 6 classrooms during the 2006 World Cup, to analyse how children used complex sentence structures in their writing on a football web-log. We explore how the confluence of a temporary, popular, global event and an online forum for communication created a moment of linguistic empowerment where pupils began to use high-level forms of language, and we consider the implications of transience and interactivity for the teaching and learning of sentence grammar.Key words: literacy, grammar, complex sentences, blogging, ICT, interactivity, digital writing, online writing, sport, football, World Cup Kicking off . . .''I think that if England are winning comfortably then I would put on Theo so he can get past the tired defenders. But if England were chasing the game, then I wouldn't put him on because it puts a lot of pressure on him and he'll get frustrated and lose the ball.'' These are the words of 11-year-old Alan, written during the run of the World Cup, 2006. Alan is speculating as to whether England captain, Sven Goran Eriksson, should try out the inexperienced young player, Theo Walcott. Alan was a reluctant writer, so as teachers our first response was one of delight at the enthusiasm and exuberance with which he articulated his opinion.A closer examination of Alan's writing reveals that this pupil, whose literacy folder in school was virtually empty, has expressed his ideas using multi-clause complex sentences, which include adverbial clauses of condition, reason and result. What was making this difference to Alan's writing? He, and 2 Year 6 classes, were blogging; Alan was contributing to on an online football web-log. His blog entry is one piece of data from a wide-ranging corpus of evidence collected from a research project exploring the language affordances (Marsh, 2005, p. 4) of a global sporting event.
